There are three missions to play through each side and 25 tasks to tackle. Players who complete them all will be rewarded with an additional playable character in the shape of Magik.

Marvel: Avengers Alliance, which went live in March, casts players as S.H.I.E.L.D. agents and combines team-based combat with role-playing elements.

For the core missions, players must recruit a team of superheroes to thwart a team of Marvel villains, with Spider-Man, Iron Man, Captain America, Thor, Black Widow, Hulk and other Marvel characters available to enlist.
